The shop Si listed even has items' prices in € for those who do not want to live in splendid isolation.
@Cor
What is the sound level of that contraption you show? I tried those bevel gears once and thought I got a coffee grinder in operation.

Also for those who value Independence, the prices can be seen in £ and $ as well. ;)

Hi Helmut :wave:


If you're still running your 'grinder', check these out...





...the 'Peltor X3A' really is a marvelous choice.

I personally recommend them. :bg:


The X5 will cut a couple of extra dB at 'certain' frequencies...

...but you do pay a severe weight & bulk penalty for that teeny-weeny bit more silence.


Don't go less than the X3A though, they just aint the same cuppa tea...

...urm ... I mean coffee.


:brill:


Si.

The 'Plastruct' channel bolster for the front archbar, has been 'welded' in place.

The truck is wholly 'hunkered' & horizontal. :P





Since I wanted the cab to be easily removable from the chassis...

...I had to figure out a simple fixing method.


A M4 'Allen' head machine-screw goes through the truck, bolster & chassis...

...into a M4 threaded-bush, which has been epoxied directly above, under the hood.


Some LOW center of gravity lead weighting, has been epoxied in at the same time also.

The front-end has a 'nice' amount of downforce on the electrical pickup modded archbar.


:moose:


Si.


The 6ft mahogany timber just behind the front truck...

...is just a 'prop' while Wolfy figures out how to fix the 'faux chain-drive' to the chassis !

no idee how much the noise level is, but I think it will be lowit is the last part of the drive train, these gears are on a low rpm, and they are from plastic.

I think that if I had found a worm-gear that was OK for a 3mm shaft...

...I probably may have just taken the conventional approach & made a worm/spur gear type drive-train.


Of course there would have been a SERIOUS reduction in the gear-ratio with that setup.

Quite possibly a higher RPM motor-gearbox could be needed.


Also the motor 'hanging down' below the chassis is likely...

...we are talking about a 1/2" dia. wheelset here !





I also have numerous small pinions & angled spur-gears, which are used in slotcars.

The problem with these however, is obviously that the motor has to be mounted 'in-line' with the drive-axle.

Fine for an F1 car, but not so great having a motor 'skimming the rails' 1mm above the railhead. :shocked:


The way it has worked out though, as you can see...

...there is no 'big lump' under the chassis...

...only the faux-chain & small 8mm faux-sprocket are visible beneath the railtruck. :cool:


:moose:


Si.


I have been messing about with building a new small crane as well...

...maybe one or two 'in progress' pix later  .  .  .  :slow:


;)

I actually like a bit of noise, some guys pay big bucks for such things. Very cool drive train.

That's working out very nicely Si. If it runs as well as it looks, it'll be an ace vehicle.

I'm slowing collecting the necessary parts to build my own.  I have a plan, and the motor has been ordered.  Need to think about putting in R/C.

A while back I searched high & low on the net, for miniature chain-drive components.

I was kinda surprised that I only managed to find 1 option out there.

I believe the miniature Delrin(TM) chain & sprockets I found, are the same as that sold by Grandt-Line.



I've never actually seen the Grandt-Line chain to confirm this.

Also, unless anyone can tell me different...

...Grandt-Line stuff can be difficult to get in the U.K. unless you wanna pay high P&P from the U.S.


It does appear to be the same stuff as this though.







The Delrin(TM) chain is about 2x4mm

The smallest sprockets are 8-tooth, with 2mm, 3mm or 1/8" bores & 0.371" diameter.








Quite BIG for a 1:35 scale 'visible' chain-drive.

But I just bought a couple of Inches of chain & an 8-tooth sprocket, to have a look-see !


:moose:


Si.


I did also look at Tamiya 1:12 scale metal motorcycle chain.
Limited sprockets available, looks hard to 'split & join', and is BIG $$$ !

I also looked at 'Fusee chain' as used in vintage clock & watch making.

Maybe a bit more about that later  .  .  .

Really cool looking chain. Have you checked out SERV-O-LINK (I believe) which has miniature chains & sprockets. That stuff interests me, as if I don't have enough to do already!

Woodie
